Simplistically, Tiscali's combined package means that the cost of your line rental (which you currently pay to BT) will be included in the price of the Tiscali package.
These packages are being rolled out across the country by Tiscali and are due to arrive in my area next month.
This is what it will mean to me:
I currently pay Tiscali £17.99 per month for up to 8mb plus free phone calls 24/7. I also pay £11.00 per month to BT for their basic (Option 1) line rental.
If/when I decide to change to the Tiscali combined package, I will pay them £19.99 per month (an increase of £2.00) but that will include the line rental. I will pay nothing to BT. Effectively I will be £9 per month better off.
However, there is a one-off £30 'connection' charge and I will have to start a new 12 month contract with Tiscali.
Still a damn good deal to my mind.
